For this lab we return to Fire Service Coverage seeking to assess tradeoffs in service against costs of maintaining different levels of stations.
Instead of covering all demand, the modeling approach tries to maximize the demand covered.
Specifically, we will employ the maximal covering location problem.
Instead of minimizing the number of facilities needed in a previous lab, we now introduce a parameter, $p$, representing a fixed number of facilities to keep in the system.
In Lab 4, there are three research questions we want to look into.
The coverage standard for this lab will be fixed at 8000m.
S = 8000
# Note: it might take time, as FD is a huge file.
FDs = gpd.read_file("Data/California_Fire_Districts.shp") # load a shapefile containing California Fire District here
blocks = gpd.read_file("Data/sbBlocks_pop.shp") # Load a shapefile containing Santa Barbara County blocks here
stations = gpd.read_file("Data/Fire_Stations_SBC.shp") # Load a shapefile containing Fire Stations in Santa Barbara County here
There are many Fire Districts in California.
We are only going to focus in the "Santa Barbara County Fire District".
In the second map, note that there are many other Fire Districts in Santa Barbara County.
Though it's not shown on the map, they have some overlapping area, which means the area is co-operated by multiple Fire Districts.

In Lab 2, we discovered that different Coverage Distance Standard can impact the coverage analysis result.
In Lab 4, we can discover how different demand representation makes difference.

Looking at the scatterplots, it seems that SBC_FD would be able to achieve coverage within several percent of current coverage with about half the number of current stations. Specifically, the curve has almost completely flattened at 15, so some minor cut in coverage could see even less stations being sufficient for coverage.
From the fishnet points, it seems that a coarser representation of demand points leads to a quicker convergence in the scatterplot to about full coverage, and also makes the slope greater. Finer representations have slower convergence, but this also most likely is more accurate for capturing the scale of demand for this type of service.
